Find the nonpermissible replacement for the variable in this expression. 5x/6x+3 a. -2 b.-1/2 c. 0 d. 1/2

For this case we have the following equation:
 5x / 6x + 3
 The denominator of the equation must be different from zero.
 Therefore, we have:
 6x + 3 = 0
 From here, we clear x:
 6x = -3
 x = -3/6
 x = -1/2
 
 the nonpermissible replacement for the variable in this expression is:
 B.-1/2

Ngl I’m kinda bad at math but imma try and help out
